CY7C65640A: TetraHub™ High Speed USB Hub Controller

Cypress’s TetraHub™ is a high performance self powered Universal Serial Bus (USB) 2.0 hub. The Tetra architecture provides four downstream USB ports, with a Transaction Translator (TT) for each port, making it the highest performing hub possible. This single-chip device incorporates one upstream and four downstream USB transceivers, a serial Interface Engine (SIE), USB hub controller and repeater, and four TTs. It is suitable for standalone hubs, motherboard hubs, and monitor hub applications.

Being a fixed-function USB device, there is no risk or added engineering effort required for firmware development. The developer does not need to write any firmware for their  design.
